Hi,
i have an 89 trans am GTA. After installing my radio i realized that my dash lights are not working. I had to hard wire the radio in because the factory plug was cut out. i followed a wire diagram to hook the radio up and everything seems to be working fine other than my dash lights. i had another radio hardwired in before i installed this one and the dash lights worked. my taillights are on and i checked all the fuses. are there any fuses under the hood? Ive had this car for about a year and im still learning more about it so if anyone has any info i would greatly appreciate it.

Thanks

 

I am not sure about an 89 T/A, my experience has been with 87 and older GM harnesses, but the only direct connection to the dash lights from the radio would be a wire that turns on the internal bulb in the factory radio when the lights are on. The 70's GM radios I believe this wire was grey, then you had a yellow for hot Newer harness I don't remember for sure what color it is but I think it is grey like the rest of the interior lighting wires ( like to the under dash lights, console lights ) Guessing the problem might be this wire is connected to the radio where it shouldn't be? hard to know. And there might be a couple fuses under the hood but they would not have anything to do with the interior items. GM pretty much kept everything on the main fuse panel under the dash.

 

thanks. il go back and check wires for power now that i have an idea of what im looking for.
